Whether you choose to ignore or allow duplicate AS4 message IDs, the option applies
to all AS4 messages received by the community, unless you define exceptions. You can
set up the following exceptions to these options:

Click
Add an exception for a partner to create a partner-specific exception.

Click
Add an exception for a category to create an exception for a partner collaboration category. A collaboration category
is a group of partners who have common collaboration settings.

Click
Add an exception for a trading pickup to create an exception for messages received by the community through a specific
community trading pickup.

Click
Add an exception for a partner's web services or AS4 delivery to create an exception for messages received synchronously through a partner web
service or AS4 delivery.

You can add multiple partners, categories or exchange points to the exceptions lists.
Activator applies the opposite of the selected behavior to any partners, collaboration categories,
or trading pickups that display in the exceptions lists.
